Inquiry about GS1 DataMatrix with Auto-Increment Serial Numbers at Fulfillment

vivekchodvadiya

Hello ATUM Support Team,

I am currently using ATUM Inventory Management for WooCommerce and evaluating whether ATUM can support a specific barcode workflow that we require.

Our Use Case

WooCommerce variable products

Each variation has a static GTIN

We use GS1 DataMatrix barcodes with multiple Application Identifiers, for example:

(01) GTIN-14

(13) Production Date

(21) Serial Number

Example encoded value:

01006287740720251325011721CAPDAM-RLABL-2500001

What We Need

Print one GS1 DataMatrix label per order at fulfillment

The serial number (AI 21) must:

Auto-increment globally (e.g. 2500001, 2500002, 2500003…)

Be unique per order

Be saved with the order for re-printing/auditing

Printing is done on a normal printer (PDF or browser print)

Questions

Does ATUM currently support GS1-encoded DataMatrix strings (with AIs like 01, 13, 21), not just plain GTIN values?

Is there any built-in functionality in ATUM to auto-generate and increment serial numbers at order fulfillment?

Can ATUM generate barcodes at order level (not product level), and store the generated value in order metadata?

If this is not supported out of the box, do you have:

An add-on,

A recommended workflow,

Or documented hooks/filters that can be used to implement this cleanly?

We want to understand whether ATUM can handle this requirement natively, or if a custom integration alongside ATUM would be the correct approach.

Thank you for your time and guidance.

Best regards,
Vivek Chodvadiya

Hi vivekchodvadiya

Does ATUM currently support GS1-encoded DataMatrix strings (with AIs like 01, 13, 21), not just plain GTIN values?

Here you can see all the barcodes that are supported by the Barcodes PRO addon:

Is there any built-in functionality in ATUM to auto-generate and increment serial numbers at order fulfillment?

ATUM can only auto-generate a serial number for Purchase Orders with the PO PRO addon.
What you need would require custom coding.

Can ATUM generate barcodes at order level (not product level), and store the generated value in order metadata?

No. That is very specific to your use case. It would require custom coding.

If this is not supported out of the box, do you have:
An add-on,
A recommended workflow,
Or documented hooks/filters that can be used to implement this cleanly?

This seems very specific. I don't think you will find something that works as you expect out of the box.
But you can achieve everything with custom coding.
Sadly, we don't have any developer documentation. You can find a developer to assist you with this, or we could provide such a service if needed.

Best Regards,

Hi Salva,

Thank you for the detailed response — it helped clarify the current limitations.

I want to confirm one specific requirement clearly to ensure we are aligned:

Our use case requires unit-level serialization, meaning:

Each physical unit of the same product SKU has a unique serial number
Serial numbers are tracked stock-wise, not just at product or PO level
At fulfillment, each sold unit is associated with its own unique serial and stored against the order (order item / metadata)
Single warehouse only (no multi-location complexity)

Based on your response, I want to explicitly confirm the following:

Does ATUM (core or any PRO add-on) currently support true unit-level serialization per product out of the box?
(i.e., tracking individual items with unique serials within available stock)

If not supported natively:

Is there any recommended ATUM workflow to approximate this?
Are there stable hooks/actions/filters exposed for:
Assigning serial numbers at order fulfillment
Persisting serials per order item
Decrementing serialized stock correctly

Can ATUM Barcodes PRO or PO PRO be realistically extended (via custom code) to support:

GS1 AI (21) serial numbers per unit
Serial assignment at sales order level, not just purchase order level
I understand this may require custom development; however, we need to determine whether ATUM is a technically suitable foundation for serialized inventory versus choosing a serialization-first solution.

A simple Yes / No on native unit-level serialization support would help us make a decision quickly.

Thanks again for your support.

Best regards,
Vivek

No. The serializations we have in PO PRO are only for POs, not for products.

It's up to you how to develop this. We don't have any recommendations here.
Just do whatever fits better with your business logic.

Can ATUM Barcodes PRO or PO PRO be realistically extended (via custom code) to support:

All the ATUM plugins can be extended. We have many hooks in place (although they are not documented). And any good WordPress developer can find and use them.
But custom coding is out of the scope of our support service.

Salva.
