1. The spreadsheet that runs the business
01The real stock count, the job costing sheet, the consolidation workbook, the sales tax by state. Each exists because QuickBooks cannot hold that information in a usable form. In an ERP those are reports from the ledger, because inventory, projects, entities and tax live in the same system as the accounts. If your month-end depends on a spreadsheet only one person understands, that is sign one.
2. Inventory the accountant does not trust
02QuickBooks inventory works for a single location with simple items. It strains under multiple warehouses, lots and serials, product variants and returns across channels, and the balance sheet figure drifts from the shelves. Tellency posts every stock movement to the ledger as it happens and records freight and duty against the purchases they belong to, so the inventory value and the warehouse count are the same number.
3. More than one company file
03The second entity, the holding company or the second franchise location is where accounting software starts to hurt: two closes, intercompany by hand, a consolidation spreadsheet. Franchise operators feel this first, and it is one of the most common reasons businesses search for a QuickBooks alternative. Tellency runs multiple entities on one ledger with consolidated reporting as a filter.
4. Production that QuickBooks cannot cost
04Assemblies are not manufacturing. If you build to order, consume components through work orders, absorb labor and overhead, track scrap or need a real finished-goods cost, you need bills of materials and work orders that post to the ledger. Tellency's manufacturing module does that, and the shop floor and the P&L agree.
5. Sales tax by jurisdiction, or GST/HST/QST by place of supply
05A US business selling into several states needs rates by jurisdiction, exemption certificates on file and returns by state. A Canadian business selling across provinces needs place-of-supply rules for GST, HST, PST and QST and returns produced from the ledger. QuickBooks handles tax by code; an ERP handles it by rule. Tellency configures your provinces and states at implementation.
6. Payroll and operations in different worlds
06When payroll runs in one system, time is tracked in another and jobs are costed in a third, labor never lands on the job or the location it belongs to. Tellency runs CRA or US payroll on the same ledger as projects, production and locations, so labor cost flows to where it was incurred from one pay run, and year-end T4s, W-2s and 1099s come from reconciled data.
7. Access from anywhere, by role
07A warehouse receiving stock, a sales team on the road, a franchisee in another city and an accountant in another province all need different views of the same data. QuickBooks Online gives everyone the same accounting screens; Desktop gives them a hosted Windows session. Tellency is cloud-based on a dedicated instance with roles for the counter, the warehouse, the sales desk, the franchisee and the owners.
What migration actually involves
08Chart of accounts, customers, vendors, items, inventory quantities, open receivables and payables and historical balances are exported from QuickBooks and loaded into your Tellency instance. Balances are reconciled to your closing trial balance, the team is trained on their roles, and a parallel month-end is run before cut-over. Most QuickBooks migrations complete within the one to four week go-live window, and your QuickBooks file stays available for historical lookups.
