When a client lands six or twelve months behind, the instinct is to start clicking through transactions — but that’s exactly how catch-up work eats a week. To reconcile months of transactions fast, you need an order of operations that front-loads the data and saves reconciliation for last. Here’s the workflow.
The principle: import coded, then reconcile by month
The slow way is to import raw transactions and code them inside reconciliation, month after month. The fast way is to catch up bookkeeping with batch import — get every transaction in already categorized, then run a clean monthly reconciliation as a check rather than as the place you do the coding.
Step 1 — Gather every statement first
Pull all the bank and credit-card statements for the full catch-up period before you touch the books. Reconciling fast depends on having the complete picture up front, not discovering a missing month halfway through.
Step 2 — Convert and code in batches
Rather than hand-key, convert each statement and code it, so you can bulk import transactions that are already classified. This collapses the two slowest steps — data entry and categorization — into one pass.
This is the gap I built Bookmonstic for. (Disclosure: I’m a CPA and Bookmonstic is my own tool.) It reads PDF/CSV/Excel statements, categorizes every transaction, and exports a QuickBooks or Xero import file — coded and ready — so months of history go in without line-by-line entry. You review exceptions and import.
Step 3 — Reconcile month by month
Now run monthly reconciliation in order, one month at a time. Because the data is already coded, each month is a tie-out: confirm the ending balance matches the statement, clear anything that doesn’t, and lock the period before moving on. Locking as you go stops a later fix from quietly reopening an earlier month.
Step 4 — Work the exceptions, not the whole pile
Whatever the import flagged as uncertain becomes your short review list. You’re spending judgment only on the genuinely ambiguous items, not re-deciding every transaction.

Frequently asked questions
What’s the fastest order for catch-up reconciliation? Gather all statements, import them already coded, then reconcile month by month as a tie-out — don’t code inside reconciliation.
Should I reconcile all months at once or one at a time? One month at a time, in order, locking each period as you finish so later changes don’t reopen earlier months.
How do I avoid recoding everything if a reconciliation fails? Import coded data and lock each reconciled month; failures then point to a specific month rather than forcing a redo of the whole period.
Can I batch-import months of history at once? Yes — convert and code the statements into import files and bring them in together, rather than keying each transaction.
