EDI 810 — Invoice

Purpose

Inform the Retailer of the cost the retailer must pay the supplier for a given order. Originates with the Supplier, sent to FLX, then Retailer gets it.

In Plain English

The 810 is the bill. Once the supplier has shipped an order (confirmed via 856), they send an invoice telling the retailer how much is owed for which items. Flxpoint uses the 810 to reconcile the cost side of the order — matching it against the 850 line prices and the 856 shipment — and then passes it to the retailer's finance or accounting system. Because the 810 drives payment, every element has to be precise: the invoice total must equal the sum of line items plus freight minus allowances, the decimals must follow Flxpoint's implied-decimal convention (TDS and SAC amounts are cents), and the REF*DP department code is mandatory. An 810 that fails validation blocks the payment cycle for that order until the supplier fixes and resends it — which is why the FLX team tracks 810 rejections closely.

Frequency

Within 24 hours of shipment. Hourly recommended, daily minimum.

Business Rules

Invoice data only accepted for items that have been shipped (856 must come first)
Must include PO number and UPC/EAN/SKU matching the original 850
Retailer determines if invoices are for cost of goods only or include shipping/handling
If supplier ships on retailer's shipping account → no shipping/handling charges in invoice
Payment terms are between Retailer and Supplier — FLX does not set them
Invoice date must be current or within 17 months (not future, not too old)
TDS uses implied decimals: $12.00 → 1200
IT1 unit price does NOT use implied decimals: $15.95 → 15.95

Not Used by FLX in IT1 Loop:

CTP (Pricing Information) — Generic X12 supports a CTP segment inside the IT1 loop for per-item price breakdowns. FLX does not process this segment — do not include it.
SAC (per line item) — Generic X12 supports allowances and charges at the line-item level. FLX only reads the summary-level SAC segment (outside the IT1 loop) and only for code G821 (outbound freight).

`AFEE`	Fee
`C310`	Discount
`D240`	Freight
`G740`	Service Charge

Note: FLX only supports G821 for shipping charges. Other SAC codes exist in the X12 standard but FLX does not process them.

FLX only accepts SAC code G821 (Outbound Freight) at summary level. Detail-level SAC (inside the IT1 loop) is ignored. Other X12 examples show codes like D240 (discount) — FLX does not process those.

Validation Notes

FLX-Specific Requirements vs Generic X12

Field	FLX Spec	Generic 004010	Impact
REF*DP	M (always "0000")	Optional	FLX stricter — department number required
SAC codes	Whitelist: `G821`/`C310`/`D240`/`F050`	Broader X12 list (AFEE, G740, H750, etc.)	FLX processes only codes in the whitelist. `G821` remains the primary shipping code.
IT1 extra qualifier pairs	Single pair only	Supports multiple qualifier/ID pairs	Generic X12 more permissive
CTP segment	Not Used — FLX ignores	Optional (detail level pricing)	Do not include; generic X12 allows but FLX skips
SAC at detail level	Not Used — FLX ignores	Optional (per-item charges)	Only summary-level SAC (G821) is processed
ISS weight units	LB, OZ, 50 (Kg)	LB, OZ, 50 (Actual Kilograms)	Match
IT104 format	NO implied decimal (15.95)	Type R (real number)	Match
TDS format	IMPLIED decimal ($12→1200)	Type N2 (2 implied decimals)	Match

Common Validation Failures

BIG01 date in future — Rejected
BIG01 date >17 months old — Rejected
ITD conditional logic violated — Discount fields without proper pairing
SAC with unsupported code — May pass generic validation but FLX won't process it
TDS without implied decimal — Sending 12.00 instead of 1200

Notes:

Two invoices for the two POs in the 850 example
Each has $5.00 shipping charge (SACCG821***500)
First invoice: 1 item @ $14.40, total $19.40 (TDS*1940)
Second invoice: 2 items @ $27.50 each = $55 + $5 shipping + $5 unrepresented = $65 (TDS*6500)
- The extra $5 cannot currently be represented in an 810 segment
