Weaver + QuickBooks
Keep the ledger your accountant loves. Add the CRM, projects, inventory, and real‑time analytics your business has outgrown — all on one data backbone.
Most “graduate from QuickBooks” pitches mean a 9‑month migration, a furious controller, and a six‑figure ERP bill — the same pattern McKinsey documented across large IT projects[141] and Standish's long-running CHAOS reports continue to track[140]. Weaver takes a different path: keep QuickBooks as your system of record for the GL, and let Weaver become everything around it.
QuickBooks stays the source of truth for chart of accounts, journal entries, and tax filings. Your accountant doesn’t learn a new tool.
CRM, projects, inventory, procurement, billing automation, BI — the things QuickBooks was never built to do — live in Weaver and sync both ways.
Every customer, invoice, and transaction lands in one normalized model. No more spreadsheet reconciliations across five tools.
QuickBooks is a beautiful ledger. It is not an ERP. Sound familiar?
Three steps. No migration. Live in days, not quarters.
OAuth into QuickBooks Online (or sync QuickBooks Desktop). Weaver pulls in your customers, vendors, items, and historical transactions in minutes.
Turn on the modules you need — CRM, projects, inventory, expenses, billing, BI. Each one writes back to QuickBooks where it should, and lives in Weaver where it shouldn’t pollute the GL.
Pipeline, project margin, cash position, customer LTV — all live, all reconciled, all on one backbone. Your accountant still closes the books in QuickBooks.
Same ledger. Vastly different operating system.
