You don't have to rip out QuickBooks to grow up.

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.

Keep your GL

QuickBooks stays the source of truth for chart of accounts, journal entries, and tax filings. Your accountant doesn’t learn a new tool.

Add the missing 80%

CRM, projects, inventory, procurement, billing automation, BI — the things QuickBooks was never built to do — live in Weaver and sync both ways.

One data backbone

Every customer, invoice, and transaction lands in one normalized model. No more spreadsheet reconciliations across five tools.

The wall every QuickBooks shop hits.

QuickBooks is a beautiful ledger. It is not an ERP. Sound familiar?

  • ✗Sales lives in a spreadsheet (or worse, in someone’s head).
  • ✗Project profitability is a guess until two weeks after the month closes.
  • ✗Inventory and COGS are reconciled by hand.
  • ✗You pay for QuickBooks, HubSpot, Asana, an inventory tool, and a BI tool — and none of them agree on revenue.
  • ✗Every executive question becomes a CSV export.

How Weaver turns QuickBooks into an ERP.

Three steps. No migration. Live in days, not quarters.

01

Connect QuickBooks

OAuth into QuickBooks Online (or sync QuickBooks Desktop). Weaver pulls in your customers, vendors, items, and historical transactions in minutes.

02

Layer on Weaver

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.

03

Run the business in real time

Pipeline, project margin, cash position, customer LTV — all live, all reconciled, all on one backbone. Your accountant still closes the books in QuickBooks.

QuickBooks alone vs. QuickBooks + Weaver

Same ledger. Vastly different operating system.

Frequently asked

Weaver + QuickBooks — common questions

Do I have to migrate off QuickBooks to use Weaver?
No. QuickBooks stays the system of record for the general ledger — chart of accounts, journal entries, tax filings. Your accountant doesn't learn a new tool. Weaver becomes everything around it: CRM, projects, inventory, procurement, billing automation, and BI, all syncing both ways with QuickBooks Online.
What does Weaver add on top of QuickBooks?
The 80% QuickBooks was never built to do: a real CRM, project profitability, inventory that reconciles to GL, procurement, automated billing, expense management, and real-time business intelligence. All on a single normalized data backbone, so customers, invoices, and transactions land in one model instead of being copied across five tools.
Does Weaver sync both ways with QuickBooks?
Yes. Customers, invoices, vendors, items, and journal entries flow in both directions. When sales books a deal in Weaver's CRM, the invoice posts to QuickBooks. When your accountant categorizes an expense in QuickBooks, the project profitability view in Weaver updates immediately.
Is this for small businesses or enterprise?
Weaver-on-QuickBooks is targeted at the segment that has outgrown spreadsheets and bolt-ons but isn't ready for the 9-month NetSuite or SAP migration that McKinsey and the Standish Group document as the failure mode. Typical fit: 10–250 employees, on QuickBooks Online, with multiple operational tools that have stopped reconciling.
How long does the Weaver-on-QuickBooks setup take?
Implementation is measured in days, not quarters, because the GL and chart of accounts already exist in QuickBooks. Weaver imports them, layers the operational apps on top, and turns on the two-way sync. The controller keeps doing what they do; the operating team gets the apps they were missing.
What happens to my historical QuickBooks data?
It stays in QuickBooks. Weaver reads historical transactions for reporting and reconciliation, but does not move or duplicate them. Future transactions can originate in either system and post to the other via the live sync.
