You already know you’re behind. You don’t need someone to explain what catch-up bookkeeping is or how it’s different from a cleanup — if that’s the question on your mind, I’ve written about that split separately. What you actually want to know is more practical: if you hire someone for this, what happens next? What do you have to do? How long does it take, and what shows up in your inbox along the way?
Here’s what a real catch-up project looks like from the inside, phase by phase.
The First Week Is Mostly About Access, Not Entry
Nothing gets entered in week one. The first few days are spent getting me into your world: an accountant invite to QuickBooks or Xero, PDFs or a login for your bank and credit card statements, and any merchant processor accounts — Stripe, Square, PayPal — that touch your revenue.
This is the part clients underestimate. If you don’t have every statement for the gap period readily available, tracking them down can genuinely take longer than the data entry that follows. Banks usually let you pull statements online going back a couple of years; older than that sometimes means a call to the bank or a request through your online portal that takes a few business days to fulfill. Start this early and it stops being a bottleneck.
While that’s happening, I’m also doing a quick pass on your chart of accounts. Not fixing anything yet — just making sure the account structure makes sense before a single transaction lands in it. Entering months of data into a chart of accounts that needs restructuring means redoing the categorization later, so this check happens first.
Then It Becomes a Month-by-Month Rhythm
Once access and documents are in hand, the work settles into a pattern: one month at a time, in order, oldest first.
For recent months, bank feeds can usually pull transactions directly into the software — but most banks only feed back about 90 days. Anything older than that gets entered from the statement PDFs directly, line by line. That’s the part that actually eats the hours: pulling a transaction off a statement, deciding what it is, and assigning it to the right account.
Categorization is where judgment matters more than speed. A $340 charge at a hardware store could be job materials, office supplies, or a personal purchase that shouldn’t be on the business card at all. An owner transfer needs to be recorded as a draw, not an expense, or it will quietly distort your profit and loss. This is also where I flag anything that looks like it needs your input — a charge I can’t identify, a deposit that doesn’t match any invoice, a transaction split between business and personal use.
You’ll get short, specific questions during this phase, not a long form to fill out. Something like: “Is the $1,200 to ‘J. Ramirez’ on 4/12 a contractor payment or a personal transfer?” A one-line answer is usually all it takes to keep things moving.
Reconciliation Is Where the Project Proves Itself
At the end of each month’s entry, that account gets reconciled against the actual bank statement — balance to balance, transaction to transaction, until the difference is zero.
This step matters more than it sounds like it should, because it’s the only real check on the whole month’s work. If everything lines up, you know the month is genuinely complete, not just “entered.” If it doesn’t line up, that’s useful information too — it usually means a transaction was missed, duplicated, or misdated, and it gets tracked down before moving to the next month rather than left to compound.
Occasionally a month won’t reconcile because of something that predates the catch-up gap entirely — an old unresolved discrepancy sitting underneath everything. When that happens, I’ll tell you plainly rather than quietly absorbing extra hours into the estimate: that specific piece has shifted from catch-up into cleanup, and I’ll explain what it will take before doing the extra work.
What the Communication Actually Looks Like
You are not going to hear from me every day, and you shouldn’t expect to. For a project running a few weeks, a realistic rhythm is a short check-in roughly once a week: where things stand, which months are done, and any questions that came up along the way. If something needs your input to keep moving, that comes as a quick, specific message rather than sitting in a queue.
The one thing I try never to do is go dark for weeks and then resurface with a finished file and no context. You should always know, roughly, where your project stands.
What Determines How Long It Takes
The size of the gap and the number of accounts involved are the two biggest factors — twelve months across one checking account is a different project than eighteen months across a checking account, two cards, and a merchant processor. Transaction volume matters too; a high-volume retail business has more line items per month than a low-volume service business, even over the same time period.
If you want a sense of scope before you talk to anyone, the cleanup cost calculator will give you a ballpark based on how far behind you are and how many accounts you’re running. If you’re not sure how healthy your books are to begin with, the free health check is a faster way to find out than guessing.
What You Actually Get at the End
When every month is entered and reconciled, you get a clean profit and loss and balance sheet for the entire caught-up period — the same reports your CPA needs for a return, a lender needs for an application, or you need just to know where you actually stand. Nothing about the deliverable is provisional; every month in it has been checked against your bank, not just typed in and left alone.
From there, the honest next question is what keeps the books from falling behind again. That’s a separate conversation, but it’s worth having once the catch-up itself is done.
