Review feature matrices carefully. Do you need advanced inventory costing, budgets, classes or tracking categories, consolidated reporting, or localized taxes? Match needs to tiers, not marketing gloss. Confirm API call limits, data retention policies, and storage caps, especially if you will sync documents or push heavy volumes from connected apps.
Enter the correct fiscal year‑end, base currency, accounting method, and default tax codes before importing anything. Verify rounding precision and number formats match your exports. Establish standard document numbering to avoid collisions. These alignment choices reduce rework and keep reports consistent across audits, lenders, and future budgeting conversations.
Turn on multifactor authentication, require strong passwords, and enable SSO if available. Restrict admin rights to the few who truly need them and record why. Keep an incident response checklist handy. A little discipline now protects payroll, customer data, and banking connections from heartbreaking, preventable breaches.
List each source column and its destination, including formats, required values, defaults, and transformation notes. Capture tax behavior, item types, and contact categories. Share the draft with operations, sales, and finance. When everyone agrees on definitions, trial imports become quick confirmations instead of painful, circular debates.
Fix malformed dates, standardize phone formats, and normalize capitalization so matching and deduplication work properly. Remove archived contacts, empty address lines, and inactive items. Split multi‑line addresses into consistent fields. Clean data produces beautiful reports, faster searches, and far fewer confusing errors during the actual import.
Create a trial company or dedicated test org. Import a single month of representative data, including invoices, bills, payments, and bank feeds. Have a manager and the bookkeeper review screens and reports. Record surprises, adjust mappings, and repeat. Iteration now saves nights and weekends later.
Generate side‑by‑side statements for the same dates. Use identical filters, accrual or cash basis settings, and currency options. Document each variance with a short note and resolution. This record becomes training gold for new hires and a sanity check when audits or lender reviews appear.
Complete formal reconciliations for bank, card, and petty cash. Match loan statements to amortization schedules. Tie accounts receivable and payable to aged reports. Confirm sales tax balances with filed returns. Checking everything once prevents repetitive questions later and builds durable confidence in your new daily working environment.
Set a lock date, restrict void and delete permissions, and capture screenshots of key settings. Save your reconciliation PDFs and variance log in a shared folder. Write a one‑page narrative describing the journey and decisions. Future you, and your auditor, will be astonishingly grateful.
