How does SOS Inventory integrate with QuickBooks?

SOS is built specifically as a QuickBooks Online companion: it syncs customers, vendors, items, and transactions two-way, adds true sales orders (which QBO lacks), multi-location inventory, assemblies and manufacturing, lot and serial tracking, and posts the accounting back to QBO.

What does SOS Inventory cost?

Published tiers from $69/month for the base plan, scaling past $300/month as features and users grow. Setup is self-serve; it's an add-on, not an ERP migration.

Does SOS Inventory read purchase orders that customers email me?

No. SOS gives you a proper sales-order object once the order is in the system, but a human still reads the emailed PDF and keys it in. Pairing SOS with a PO-intake tool like SideQuest closes that first step.

SOS Inventory + QuickBooks: how the integration works and what it covers

SOS Inventory exists because QuickBooks Online stops short in three places distributors feel daily: no true sales orders, thin multi-location inventory, and no manufacturing. SOS bolts all three on and keeps QBO as the books. Here's how the pairing behaves, what it costs, and the step in the order flow it deliberately doesn't touch.

What SOS adds to QBO

The integration is the product: SOS was built for QuickBooks Online rather than ported to it. It syncs customers, vendors, items, and transactions both directions and layers on the missing operations pieces: sales orders as a first-class object (QBO natively jumps from Estimate to Invoice), multi-location and bin-level inventory, assemblies and light manufacturing with BOMs and work orders, and lot and serial tracking. Accounting entries post back to QBO, so your accountant's world doesn't change.

Cost and commitment

Published tiers start at $69 a month and scale past $300 with features and seats, self-serve setup, no implementation project. As QBO add-ons go it's the established, boring-in-a-good-way choice for distributors who've outgrown QBO's inventory but aren't ready to leave QuickBooks. (Evaluating whether you need the whole platform versus just PO handling? That comparison is on the SOS Inventory alternative page.)

The step SOS leaves manual: getting the order in

SOS gives every order a proper home once it exists in the system. It does nothing about how it gets there. The customer's PO still arrives as a PDF on email, and someone still reads it, translates part numbers, and keys lines into a sales order, the same 9-to-14-minutes-per-PO tax, now typed into SOS instead of QBO.

That intake step is SideQuest's job: read the PO email from Gmail, match every line to the QuickBooks item list (exact SKU, learned cross-references, fuzzy description), check prices against the book, draft for review. Because SOS syncs its item list with QBO, the catalog SideQuest matches against is the same catalog SOS fulfills from, and the two tools sit on opposite sides of the same books without touching each other.

Which do you actually need?

Your pain	Tool
QBO can't represent my operations: sales orders, locations, assemblies	SOS Inventory ($69+/mo)
Orders arrive by email and someone retypes them all day	SideQuest ($0–$299/mo)
Both	Both. They solve different halves and share QuickBooks cleanly
