X12 and GS1 rules, checked segment by segment.
Each rule is a plain, inspectable check — not a model's best guess.
GTIN-12 Mod-10 repair
Every UP qualifier in PO1 is recomputed with the GS1 Mod-10 algorithm. Bad check digits are corrected before they reach your ASN or label.
CTT01 & SE01 recount
Line-item and segment counts are recalculated from the actual transaction set, which is the leading cause of 997 functional-acknowledgment rejections.
HL S→O→P→I hierarchy
The outbound 856 is built with shipment, order, pack and item loops, MAN*GM SSCC-18 marks and a matching CTT hash total.
Code level determinism when you need it. Browser simplicity when you do not.
The same 850 compiles to the same 856 and the same SSCC every time. No VAN mailbox, no consultant, nothing stored on a server.
What it costs compared to the usual options.
Published list prices as of October 2026. No sales call required.

Questions we hear most.
Which X12 versions does DockClear support?
ANSI X12 004010 transaction sets 850 (purchase order), 856 (advance ship notice) and 810 (invoice) segment conventions, with ~ segment and * element separators.
Do I still need a VAN or AS2 connection?
Your retailer still needs the 856 delivered. DockClear produces the compliant file; you upload it through your retailer portal or existing AS2/VAN mailbox without paying for a full EDI platform.
Are the GS1-128 labels scannable at the DC?
Yes. Labels encode AI (00) SSCC-18 with a computed Mod-10 check digit in a 4x6 layout with ship-from, ship-to, PO and carton zones. Print at 203 or 300 dpi on thermal stock.
What causes "segment count mismatch" 997 rejections?
SE01 must equal the number of segments from ST to SE inclusive, and CTT01 the number of PO1 lines. DockClear recounts both and flags the original values in the segment audit.
How does pricing compare to SPS Commerce?
A $19 Carton Pack covers a single PO end to end; the $29/month Batch plan covers unlimited POs. There is no setup fee, contract or per-document charge.
Can I import the PO into Shopify?
Yes. The Shopify PO CSV maps buyer part, vendor SKU, repaired GTIN, quantity, unit price and ship-to, ready for draft orders or a wholesale app import.
