Dext AI Assist is a bookkeeping agent inside Dext that learns how you code items and suggests the same treatment next time. On Business it is $10.50 a month as an introductory price to 31 January 2027, on top of $302.50 a year. It pays off only with enough repeat suppliers.
For a small workload the sum is short: the add-on costs $126 a year at the intro price, so it needs to save roughly 4 hours of paid time a year at $30 an hour. Whether it does depends on how many supplier receipts repeat, not on how clever the agent is.
What Dext says the add-on does
Dext launched AI Assist in March 2026, according to its release log. From its product page, it watches how you categorise items, apply tax treatments and repeat corrections, and then suggests automations for those patterns, each with its reasoning attached. When a document does not fit the pattern, it flags it for a second look rather than guessing, and you can also give it your own instructions when a new supplier or rule turns up. It currently works on items in the Costs and Sales spaces of Dext. Since July 2026 it can also create, update, merge and split line items on receipts and invoices, but only if Line Item Extraction is enabled on your account.
Dext says AI Assist runs on its own in-house models, trained on invoices, receipts and statements, and that data processed by AI Assist is never used to train external AI models.
Think of it as a junior who has watched you code the same electricity bill ten times and now offers to do number eleven. It does not know anything about your business that you have not shown it through your own decisions, which is why a brand-new account gets little from it.

Buy nowHow the review step works, and why it is the point
Dext says each suggestion can be applied, adjusted or ignored, and that you can check every suggestion before it applies or switch to an auto mode once you are comfortable. Actions stay auditable afterwards. When the AI is unsure, Dext says a human reviewer settles it and the model learns from the answer.
The safe way to use it is in three stages.
- Suggest only. Every suggestion needs your approval. Run this for a month.
- Approve in bulk for trusted suppliers. Where you approved the same suggestion every time, let it run and spot-check.
- Auto for the boring middle. Keep human review on anything above a value you choose, new suppliers and anything with a tax treatment you would want to explain to an accountant.
Our tutorial on human review for AI work describes how to set thresholds without slowing the work down.
What it costs: Business plans and practice plans
Dext lists these prices in USD on its pricing pages as read on 5 November 2026. They exclude tax and may change.
| Item | Price | What to know |
|---|---|---|
| Dext Business, annual | $302.50 a year | 250 documents a month, 5 users; "up to 20% cheaper" than monthly billing |
| Dext Business, shown per month | $25.21 a month | The annual price divided by 12, shown beside "$302.50 billed annually"; the page has a Monthly toggle and says annual is up to 20% cheaper, so monthly billing costs more |
| AI Assist add-on, Business | $10.50 a month until 31 January 2027 | Launch offer; later price not stated on the page |
| AI Assist Core guidance, practice plans | Included | A library of Dext-built guidance; the practice product page says it is free to all Dext users |
| AI Assist custom guidance, practice plans | $7 per client | The practice product page calls it $7 per client per month, a launch offer "until the end of October"; the pricing page still shows $7 a client, so confirm the current rate |
| Practice plans (Essentials, Advanced) | From $17.70 and $19.20 per client per month | Annual subscription billed monthly, 10-client minimum, rates falling as the list grows; Dext's "build your plan" tool gives a quote |
A note on the numbers: the Dext Business page shows both $302.50 and $25.21, but they are the same annual price expressed two ways, not a monthly plan at $25.21. If you choose monthly billing, expect to pay more than $25.21. On the practice side, Core guidance carries no price on the pricing page, and Dext's practice product page and its May 2026 release note both say it comes with the subscription; only custom guidance is charged.
The cost sums for a small business
An illustrative case: a print shop with one owner, a part-time bookkeeper and about 180 supplier documents a month, well inside the Business plan's 250. It already pays $302.50 a year for Dext.
| Line | Figure |
|---|---|
| Dext Business, annual | $302.50 |
| AI Assist, 12 months at $10.50 | $126.00 |
| Total in year one | $428.50 (about $35.71 a month) |
| Add-on as a share of total | 29% |
| Break-even at $30 an hour | $126 / $30 = 4.2 hours a year |
| Break-even in minutes a month | $10.50 / $30 x 60 = 21 minutes a month |
Twenty-one minutes a month is not much. If the bookkeeper currently spends 10 seconds coding each of 180 documents, that is 30 minutes, so AI Assist would need to remove nearly all of it to break even on coding alone. The case is stronger when you count the checks it runs and the corrections it saves later, and weaker when most of your suppliers are one-offs. Run a trial and measure, rather than assuming the benefit.
What a firm pays: per client, not per business
Practices that look after clients are billed differently. The $7 figure is per client per month for AI Assist custom guidance, according to Dext's practice product page, and practice plans need at least 10 clients. That page described $7 as a launch offer running to the end of October, so ask Dext for the rate that applies when you sign; the table below uses $7.
| Clients on AI Assist | Monthly at $7 a client | Yearly |
|---|---|---|
| 10 | $70 | $840 |
| 25 | $175 | $2,100 |
| 40 | $280 | $3,360 |
For a firm, the question is per client: will AI Assist save more than $7 of staff time on that client each month? At $30 an hour that is 14 minutes a client a month. Clients with many repeat transactions, such as a trades business buying from the same three merchants, clear that bar easily. A client with ten invoices a quarter does not. Turn it on for the high-volume clients first and leave the rest off.
Which workloads gain most
A trades business with repeat merchants
Fuel, materials from two or three suppliers, a van lease. Hundreds of near-identical receipts. The patterns are clear, so suggestions are right often and review is fast. This is the best case.
A yoga studio with a handful of bills
Rent, insurance, software subscriptions, a few supplies. About 25 documents a month, all of the same few suppliers. Dext's own rules for those suppliers do the job already, and AI Assist adds little. Not worth $10.50 a month on volume alone, unless it is catching data-quality errors you would otherwise miss.
A tutoring centre with seasonal spikes
Quiet months, then September and January loaded with materials and room bookings. The learning happens in busy months, and in quiet ones the add-on sits idle. Consider adding it for the busy quarter and removing it afterwards, if Dext lets you change add-ons monthly; check that on your billing page.
A wedding planner paying many different vendors
Almost every supplier is a one-off: a venue, a florist, a band. Little repetition means little to learn. AI Assist is a poor fit; clear coding rules and a good chart of accounts will serve better.
A four-week trial you can run
Dext offers a 14-day free trial and says it does not ask for card details to start it, and the AI Assist product page says the add-on is available on a free trial too. Use the trial, or the first month of the add-on, as a measured experiment.
AI Assist trial sheet (illustrative figures)
Week | Documents processed | Suggestions made | Accepted as-is | Corrected | Time spent reviewing
1 | 45 | 12 | 9 | 3 | 25 min
2 | 48 | 22 | 19 | 3 | 20 min
3 | 42 | 28 | 26 | 2 | 15 min
4 | 46 | 31 | 30 | 1 | 12 min
Acceptance rate in week 4: 30 / 31 = 97%
Time saved vs your pre-trial coding time: compare the review time to the 4-week average before the trial
The shape matters more than the exact numbers. A healthy trial shows suggestions rising as it learns and the acceptance rate climbing. If acceptance stays below about 80% after a month, it is not learning your patterns, and you should cancel or ask Dext support why.
Keep a note of the corrections, too. Corrections that cluster on one supplier tell you a rule is needed. Corrections spread across everything suggest your coding is inconsistent, which is a bookkeeping problem the agent is exposing rather than causing.
What a suggestion looks like, and what to check in it
Dext does not publish a sample screen with every field, so the example below is illustrative of the kind of decision you will be asked to approve, not a copy of Dext's interface. Imagine a tutoring centre that buys printer paper from the same merchant every month.
Suggestion (illustrative)
Supplier: office paper merchant
Pattern seen: 11 of the last 11 invoices coded to "Printing and stationery",
tax rate: standard purchases
Proposed action: apply the same coding to future invoices from this supplier
Reasoning shown: same supplier, similar line descriptions, same tax rate each time
Your options: apply / adjust / ignore
Before you click apply, check three things. First, is the pattern real? Eleven out of eleven is solid; seven out of eleven is a supplier that sells different kinds of goods and needs line-level review. Second, is the past coding right? The suggestion repeats history, so a wrong history gives a confident wrong answer. Third, would a different line on the invoice ever change the coding, such as a delivery charge, a one-off equipment purchase or an item for resale? If so, adjust the rule or leave that supplier on manual review.
A before and after for one bookkeeping week
An illustrative week for the part-time bookkeeper of a four-person print shop, handling about 45 supplier documents.
Before. She opens each new document, checks the supplier, picks the category, confirms the tax rate and publishes it to the accounting software. Where Dext's supplier rules exist, that is quick; where it does not, she thinks about each one. About 40 of 45 are repeat suppliers. Total time: about 2 hours 20 minutes, of which perhaps 35 minutes is the slower decisions on new or unusual items.
After a month of AI Assist in suggest-only mode. The repeat suppliers arrive with a proposed coding and reasoning. She approves most in a few seconds each, and spends her attention on the five new or odd items and on any that the agent flags as unsure. Total time: about 1 hour 40 minutes. She saves around 40 minutes a week, roughly 2.7 hours a month. At $30 an hour that is $80 a month against a $10.50 add-on. Those figures are invented to show the method; her own numbers will differ, and the saving shrinks if her suppliers are not repeats.
A trial that measures the "before" week properly is the only way to know. Time yourself for a normal week before switching on the trial, write it down, and compare with week four.
Three ways to get the same result, compared
| Approach | Cost | Best for | Weakness |
|---|---|---|---|
| Supplier rules in Dext, set by hand | Included in your plan; your time to set up | A stable list of suppliers coded the same way every time | Rules do not adapt; they miss new suppliers and changes |
| AI Assist on top of rules | $10.50 a month intro price on Business; Core guidance included and custom guidance $7 a client on practice plans | High volume of repeat items with some variation | Needs history; repeats past mistakes; still needs review |
| A general AI assistant reading exports | Your AI subscription; your time | One-off analysis, such as spotting odd transactions | Not connected to the posting workflow; privacy checks needed |
Start with the first. If rules cover most of your volume, the second adds little. The general-assistant route is useful for a periodic review of a month's transactions rather than daily coding; the tutorial on connecting Claude to QuickBooks read-only shows one safe way to do that.
Clean-up to do before you switch it on
A thirty-minute tidy makes a trial far more honest. Work through this list in your accounting software and Dext.
- Run a report of your ten biggest suppliers by spend and confirm each is coded to the right account.
- Merge duplicate supplier names, such as "Paper Co" and "Paper Co Ltd", because the agent will treat them as two patterns.
- Remove accounts you no longer use from the chart of accounts, so a suggestion cannot land on a dead category.
- Check that tax rates on your top suppliers are what your accountant expects.
- Decide who is the admin on the account, since Dext says only a practice admin can enable AI Assist.
- If you split mixed receipts line by line, check that Line Item Extraction is switched on, because AI Assist's line-item features depend on it.
- Write down your current weekly time on coding, so the trial has a baseline.
An owner who skips this list often decides the agent "does not work", when it was faithfully repeating a messy history. If you are unsure whether your data is in shape, our tutorial on cleaning records before you add AI covers the same principle for customer data, and it applies equally to supplier lists.
Questions to put to Dext before you commit
Because the page states the intro price only to 31 January 2027 and gives no later price, ask before you budget. A short message works.
Subject: AI Assist pricing after 31 January 2027
Hello,
We are on the Business plan and are considering the AI Assist add-on at
the introductory price. Please could you confirm in writing:
1. The monthly price after 31 January 2027.
2. Whether we can remove the add-on at any time and how that is billed.
3. Whether AI Assist counts against our 250 documents a month.
4. Which of our users can switch it on or off.
Thank you,
[your name]
Question 3 matters because of how Dext treats the document limit: its pricing page says that once you reach your monthly limit you can still upload documents, but they are not extracted until your next bill date or an upgrade. Question 2 matters because Dext's business pricing page says annual plans need 30 days' notice before renewal to cancel, while monthly plans can be cancelled any time before the renewal date.
Keep the reply with your accounting records. If the later price is double the intro price, your break-even moves from 21 minutes a month to 42, which may still be fine for a busy firm and wrong for a quiet one.
A realistic first-quarter budget
For a Business account that adds AI Assist at the intro price in November 2026, here is a simple budget that stays honest about the date. It assumes you pay $302.50 a year for the plan already.
| Month | AI Assist cost | Notes |
|---|---|---|
| November 2026 | $10.50 | Trial month, suggest-only mode |
| December 2026 | $10.50 | Measure acceptance rate and review time |
| January 2027 | $10.50 | Last month at the intro price; decide to keep or cancel |
| February 2027 onwards | Not stated on the page | Use the price Dext confirms in writing |
Three months at $10.50 is $31.50, a cheap experiment. Make the keep-or-cancel decision in the last week of January, when you have three months of data and the old price is still in force.
What this tool will not do for you
It will not set up your books, choose your tax treatment or tell you whether a spend is deductible. Dext says it works with items in the Costs and Sales spaces, so do not expect it to handle payroll, fixed assets or year-end adjustments. It speeds up repeat decisions that you or your bookkeeper have already made, and flags oddities. Anything that needs judgement still needs a person, and your accountant remains the one to ask about tax treatment.
That limit is also why it suits small workloads less than it suits busy ones. The fewer repeat decisions you have, the less there is to automate. A business with 30 documents a month should put its effort into a tidy chart of accounts and a handful of supplier rules, then revisit the question when volumes grow.
How it goes wrong
An agent that learns from your decisions also learns your mistakes. If you have been coding a supplier to the wrong account for months, AI Assist will cheerfully repeat it at speed. Before switching it on, spend half an hour cleaning up the last quarter's coding for your top ten suppliers.
The second risk is silent drift. In auto mode, a change in how a supplier invoices you, say a new tax line or a different product range, can be miscoded without anyone seeing it. A monthly spot-check of 20 randomly chosen auto-coded items takes ten minutes and catches most of it.
The third is data quality. Dext's practice product page says incomplete or incorrect document data is corrected or flagged on the way through, and the business page says documents that do not fit a pattern are flagged for a second look. Treat those flags as a to-do list for your bookkeeper, not as a clean bill of health when there are none. Dext sells data-quality checks to practices separately, as the Data health and insights add-on listed at $7.50 a client a month.
Who should say yes, and who should wait
- Say yes to a trial: you have 100 or more documents a month, mostly from repeat suppliers, and a person who will review suggestions weekly.
- Wait: fewer than about 50 documents a month, mostly one-off suppliers, or an account less than two months old.
- Firms: start with your five busiest clients and measure the per-client time saved against $7.
- Everyone: put the end of the introductory price, 31 January 2027, in your calendar and ask Dext what happens after it.

Dext AI Assist questions
Does Dext AI Assist work on a brand-new account?
Less well than on an established one. Dext says its models start from years of bookkeeping documents, but the suggestions specific to you come from your own categories, tax treatments and corrections, so it needs a history of decisions. Practices can switch on Core guidance, Dext's built-in library, from day one. Judge it after a month or two of normal work.
Who can switch Dext AI Assist on?
Dext says only a practice admin can enable it. If you are a business owner on a Business plan, check who holds the admin role on your account before you plan a trial, because a bookkeeper may need to turn it on for you.
Does it replace my bookkeeper?
No. Dext says you can check every suggestion before it applies, and that you keep the final word. It speeds up the routine coding and checking; it does not decide tax treatment for you or sign anything off. A person still reviews exceptions.
What happens when the introductory price ends?
Dext's Business page says the $10.50 a month price runs until 31 January 2027, and the product page calls it a launch offer. Dext does not state the later price there, so ask for it in writing before you rely on the intro rate for a full-year budget.
