Which accounting firm process should be automated first?

Start with client document collection. It runs for every engagement several times over, it consumes staff hours in the weeks you have none, and it needs the least professional judgment of any recurring process in the firm. Invoice preparation from time and work in progress is the close second, because the billing rules already exist and the hours are easy to count. Pick one and finish it before starting the second.

How do you decide between two processes that both look worth automating?

Multiply how often the process runs by the hours one pass costs, then divide by how much professional judgment it needs. Instinct favours whatever most recently caused a crisis; this arithmetic favours the work that quietly costs time every month. Where two processes score the same, choose the one whose result your team can see within a single cycle, because visible proof is what earns support for the next project.

How long does a first AI workflow take to reach production at an accounting firm?

A first workflow usually reaches production in three to six weeks. Two things set the pace: how quickly the firm can grant access to the systems involved, and how settled the rules are. Billing with documented rules moves fastest. A process whose rules live in one manager's head takes longer, because the rules have to be written down and agreed first. We plan the go-live around busy season rather than in the middle of it.

Who provides this kind of automation for accounting firms?

Fixed Labs builds and runs these workflows for accounting, tax and advisory firms. It records the process with the firm's own team, builds inside the systems the firm already uses, tests on real work, and runs the workflow after launch with a monthly exception report for partners. Each workflow has a fixed build fee plus a monthly fee to run it, quoted before any build starts. Its published billing work completed 513 invoices across three observed weeks at about six minutes each.

AI Workflows for Accounting Firms: Where to Start

Q: What should stay with the firm's own people?

Anything a licensed professional signs: tax positions, audit conclusions, write-downs, adjustments, client advice and any message that gives a client a conclusion. The workable design rule is to separate preparation from judgment. A draft invoice can be prepared and held for approval. A suspected bookkeeping problem can be flagged without touching the books. A payment that does not match cleanly goes to the billing manager instead of being forced through.

Every accounting firm should automate the process it repeats most often that needs the least professional judgment. For most firms that is client document collection first, then invoice preparation and work-in-progress follow-up. Pick one, run it for a full cycle beside the old way, and only then start the second.

Key takeaways

Rank the work by how often it happens and how many staff hours one pass costs, then by how little judgment it needs.
Our own rule: anything a licensed person must sign stays with that person. Automation gets them a better starting point, never a finished conclusion.
The published Fixed Labs billing work is the worked example: two weeks documenting billing rules, then 513 invoices across three observed weeks at about six minutes each, against the team's own 15-minute manual estimate.
One process at a time. A firm with one automation it trusts beats a firm with four half-built ones.

Which processes should an accounting firm automate first?

The shortlist is small, and it is the same in most firms. These six processes repeat every month, follow rules you can write down, and eat hours you can count.

Process	How often it runs	Who does it today	Judgment needed	Settle this before you build
Client document collection	Every engagement, several times	Preparers and admin staff, between other work	Low: the checklist is fixed	Who decides when an item is waived, and what happens to a client who never replies
Invoice preparation from time and WIP	Every billing cycle	Billing staff, at month end	Low: the billing rules already exist	Which held time and write-offs need a partner's decision before drafting
Work-in-progress follow-up	Weekly	Managers and partners, when they find a free hour	Low: the report already lists aged time	What the follow-up may say without a partner reading it first
Payment matching and cash application	Weekly	Accounting staff, by hand	Medium: short pays and unapplied cash need a call	Who clears anything that does not match cleanly
New-client onboarding and engagement setup	Per new client	Admin staff, across two or three systems	Low: the steps are defined	Who approves a new engagement record, and where the engagement letter lives
Monthly close review and exception routing	Monthly	Managers and reviewers	High: adjustments and client communication	Which exceptions a person must decide, and how fast

Document collection and invoice preparation are usually the two best starting points. Both run on a list that already exists, both produce a draft a person can check in minutes, and both show a result your team can feel within one cycle.

Monthly close review sits at the bottom of the list on purpose. It is valuable and it is the wrong first project, because the judgment is high and the volume is lower. Automate the work around the review first, then give the reviewer a cleaner queue.

What makes a process a good first candidate?

Four tests. A process is ready when it passes all four, and it is not ready when it fails any of them.

It repeats on a schedule you can name. Weekly or monthly, for many clients, not a handful of times a year.
The rules already exist on paper or in one person's head you can record. If two employees do the same step differently, write the difference down first.
The output is a draft a person can check. A prepared invoice, a chased document list, a matched payment batch. Not a final tax position.
You can measure the before and after. Hours per invoice, days from work done to invoice sent, aged unbilled work, open document requests per client.

If the process fails the second test, that is your first project: record how the work actually runs, end to end, while an experienced person does it.

How do you decide between two processes that both look good?

Multiply how often the process runs by the hours one pass costs, then divide by the judgment it needs. The arithmetic is crude and it beats instinct, because instinct favours the process that most recently caused a crisis over the one that quietly costs an hour every day.

For a 60-person firm, the comparison usually looks like this. Document collection runs for every engagement several times over and consumes staff hours in the weeks you have none. Invoice preparation runs once a month for every client and takes a full day of billing-staff time. Both score high. The tiebreaker is the result: document collection shows whether it worked inside one cycle, which matters when you are building support for the next project.

What does a first automation actually look like in practice?

Here is the billing work we published. Fixed Labs spent two weeks with an accounting firm's invoicing team documenting its billing rules: which held time to include, what a partner must approve, how write-offs are handled, and what makes an invoice unusual. Only then did invoice preparation go into supervised operation.

Over the next three observed weeks the workflow completed 513 invoices at about six minutes each, against the team's own estimate of 15 minutes by hand. Every invoice was approved by the billing manager or the engagement partner before it went to the client. The workflow never sent anything on its own and never adjusted work in progress.

The two weeks of rule capture are the part most firms skip. It is also the part that decides whether the automation is trusted six weeks later. If the process has to be scored before it can be scoped, use the AI readiness scorecard for CPA firms.

Which processes should stay with your people?

Every process where a licensed professional signs the answer. Tax positions, audit conclusions, write-downs, adjustments, client advice, and any communication that gives a client a conclusion.

The useful design rule is to separate preparation from judgment. A draft invoice can be prepared and held. A suspected bookkeeping problem can be flagged without touching the books. A tax notice packet can be assembled without deciding the substantive response. A payment that does not match cleanly goes to the billing manager rather than being forced through.

That boundary is also what makes the work reviewable. If the agent prepares and a person approves, you always have a record of who decided what. When you compare providers for the work, put every proposal on the same scope first: the consultant proposal comparison guide shows how.

How do you run the first one without disrupting the season?

Weeks 1-2: record one process with the person who does it today. Capture the trigger, the inputs, the exceptions and who approves the output.
Weeks 3-6: build it inside the systems your firm already runs, and test it on real invoices, documents or payments with your own staff.
Weeks 7-10: run it beside the existing process for a full cycle and compare directly rather than trusting impressions.
Weeks 11-12: fix what the cycle exposed, then extend it to the next client type or start the second process.

A first workflow usually reaches production in three to six weeks, and the range depends on how quickly we get system access and how settled the rules are. Plan the go-live around busy season rather than in the middle of it.

What should you measure once it is running?

Measure accepted work, not activity, and keep the budget beside the result: the first-workflow cost breakdown separates the build fee, the monthly run cost and your own team's review time. Invoices prepared per cycle and minutes per invoice. Days from work done to invoice sent. Aged unbilled work. Open document requests per client. First-pass acceptance: how often the reviewer accepts the output without correction, and why when they do not. Rework minutes the automation creates. And whether the recovered capacity actually went somewhere useful.

The Intuit 2026 Accountant Technology Survey found 30% of firms name manual data cleanup as the biggest blocker to advisory work, ahead of staffing shortages at 24%. That is the number to beat in your own firm: not hours saved in the abstract, but whether the time went to client work.
