3PL & logistics integration: the systems that move your freight, finally talking to each other.

Your WMS knows what's on the shelf. Your TMS knows what's on the truck. Your ERP knows what it cost, and your customer's EDI feed knows none of it. Stone Age Software LLC builds the integrations, workflows, and portals that close those gaps — so your team stops re-keying orders and starts shipping them.

We're the software team behind 3PLs, brokers, and distributors.

You move the freight; we build and support the technology that helps your people run leaner — whether that's a single-site warehouse getting off spreadsheets or a multi-client 3PL onboarding its next big-box account.

Capabilities

Six places logistics software quietly leaks money

Each of these starts as a manual workaround somebody built once to survive a busy week — and then never got to remove.

WMS & Warehouse Operations

Receiving through shipping, on a scanner instead of on paper and spreadsheets.

  • Receiving, putaway, pick/pack/ship & cycle-count workflows
  • Barcode, RF, and mobile screens built to be used wearing gloves
  • Multi-client inventory separation for 3PL operators
  • ZPL label & packing-slip printing, including print-and-apply

Case studies a receiving exception that opens its own case · label printers that stopped wedging under a receiving burst · pick and upload screens automated where no API exists · wave plans and a pick queue built from a daily backlog feed

TMS, Rating & Freight Routing

Rate-shop, tender, dispatch, and track loads without re-keying a thing.

  • Parcel, LTL & FTL carrier API and rate integrations
  • Load tendering, dispatch boards & check-call automation
  • Tracking, ETA, and proof-of-delivery capture
  • Accessorial and detention capture at the moment it happens

Case study carrier holds and wrong-city deliveries caught without a portal lookup

EDI & Trading-Partner Onboarding

New retailer or customer? Mapped, tested, and live without the chargebacks.

  • X12, EDIFACT, and RosettaNet PIP mapping, order through cash
  • AS2, SFTP, VAN, RNIF/ebMS, and REST/webhook transports
  • Retail routing-guide compliance & 997 acknowledgements
  • Chargeback root-cause analysis and prevention

3PL Billing & Freight Settlement

Bill every storage, handling, and accessorial charge you actually earned.

  • Rate engines for storage, handling & value-added services
  • Automated customer invoicing straight into accounting
  • Carrier invoice audit and reconciliation against quoted rates
  • Margin and cost-to-serve reporting per customer

Customer Portals & Visibility

Give customers a login instead of giving your team another phone call.

  • Branded 3PL portals for inventory, orders & documents
  • Dashboards for OTIF, dock-to-stock, fill rate & cost per order
  • Exception alerting on stuck orders and failed EDI
  • Scheduled reporting customers stop having to ask for
Who we build for

If freight, inventory, or purchase orders touch it, we've probably wired it

3PLs & fulfillment centers

Multi-client operations that need each new customer onboarded fast and billed correctly.

Freight brokers & forwarders

Tendering, tracking, and back-office automation that keeps margin visible per load.

Warehouse operators

Public, contract, and cold-storage sites moving off paper, whiteboards, and spreadsheets.

B2B distributors & wholesalers

EDI-heavy order flows, big-box retail compliance, and ERP integration that holds up.

Manufacturers & shippers

Inbound supplier ASNs, plant-to-DC moves, and freight spend you can finally audit.

Brands scaling into retail

Going from a webstore to Walmart, Target, or Amazon vendor requirements without panic.

Two ways in, depending on what hurts

Most logistics operations have one of two problems. Either the warehouse floor is running on paper, tribal knowledge, and a spreadsheet nobody else can open — or the floor is fine, and the pain is every trading partner demanding files in their own format on their own schedule.

They need different fixes, so we've written them up separately. Start with whichever one sounds like your Monday morning.

3PL & warehouse software EDI & B2B integration

Signals it's the warehouse

Mis-picks climbing with volume, cycle counts that never reconcile, and a supervisor who is the only one who knows where anything actually is.

Signals it's the integration

Someone re-typing orders from a PDF or portal, retail chargebacks you can't explain, and inventory that's accurate in one system and fiction in the other.

Signals it's the billing

Accessorials that never make it onto an invoice, storage billed off a month-old snapshot, and no honest answer to which customers are actually profitable. The fix usually starts with the 3PL reporting layer.

How an engagement runs

Prove it on one lane before you bet the network on it

  1. 1

    Map the flow

    We walk the actual path of an order — every system, hand-off, email, and workaround — and put numbers on where the hours go.

  2. 2

    Pilot one partner

    One customer, one lane, or one document type goes live first. Small enough to be safe, real enough to prove the payback.

  3. 3

    Roll it out

    Then it becomes a template. Each additional partner or site reuses the mapping, the tests, and the runbook.

  4. 4

    Watch it run

    Monitoring and alerting on every feed, so a failed transmission reaches you before it reaches your customer.

Engagement models

Priced for operators, not enterprise procurement

We're a small, senior team by design. You get the engineer doing the work, and a scope you can start without a steering committee.

Integration assessment

Fixed fee · 1–2 weeks

We map every system, hand-off, and manual workaround in your flow, then hand you a prioritized plan with effort and payback per item. Yours to keep, whoever builds it.

Scoped build

Fixed scope · per project

One integration, one partner, one workflow at a time — priced up front. Most first engagements are a single EDI partner or one system-to-system link.

Fractional integration team

Monthly retainer

Ongoing capacity for partner onboarding, carrier changes, peak-season prep, and the monitoring that catches a failed transmission before your customer does.

Integration targets

Platforms, formats, and partners we build against

Working with something not on this list? It's usually still a documented API, a flat file, or a database — all three of which we speak. The code lands in whatever your stack already runs — C#, Java, Python, Go, TypeScript, or plain SQL — not in a platform you have to license.

Questions we get

Straight answers

Are you a 3PL?

We are the software team behind 3PLs: we build, integrate, and support the systems logistics operators run on. When your WMS, TMS, ERP, and trading partners need to talk to each other, that is exactly what we do.

Do we have to replace our WMS or TMS?

Almost never. Most of what hurts in a logistics operation is the gaps between systems, not the systems themselves. We start by integrating and automating what you already own — and we will tell you honestly if a platform genuinely has to go.

How fast can you onboard a new EDI trading partner?

On a document set we have already mapped for you, typically days. A brand-new retailer with its own routing guide, labeling rules, and certification process is usually two to four weeks, most of which is their testing cycle rather than our build.

Can you work with our VAN, or do we need one?

Either way. We work through existing VANs and translators, and we can also run direct AS2 or SFTP connections and modern REST/webhook APIs where a partner supports them — which often trims per-character VAN fees along the way.

What happens during peak season?

We plan around it: load-test before Q4, freeze risky changes through peak, and stay reachable for the cutover-sensitive weeks. We would rather ship an integration in August than firefight it in November.

We are a small operation. Is this worth it?

Often more so. A single-site 3PL with three EDI customers loses just as many hours to manual re-keying as a large one, with fewer people to absorb it. We scope small fixed-price pieces so you can see the return before committing to more.

Guides

Guides written from the questions this practice gets

The things an operations person types into a search box the week a retailer, a depositor or an auditor asks: what the 940 and 945 must carry, why a deduction happened and which file shows it, what a first Walmart connection really involves, which accessorials never reach the invoice, whether a customer's PIPs are the same job as X12. Each answered in full, and each linking back to the row above that does the work.

EDI & Trading-Partner Onboarding

EDI 940 vs 945: what a 3PL actually needs to support

The 940 is the order in and the 945 is the answer back. What each one carries, where the mismatches come from, and the three documents that complete the warehouse set.

EDI & Trading-Partner Onboarding

Why retail chargebacks happen and how to trace them to the file

A deduction is a symptom. The cause is in the ASN, the label, the acknowledgement log or the clock, and each one leaves evidence in a file you already have.

EDI & Trading-Partner Onboarding

What it really takes to onboard a Walmart EDI connection

The weeks go to the test cycle, the labels and the ASN clock, not to the mapping. The order of work for a first Walmart connection, and what to have ready before it starts.

3PL Billing & Freight Settlement

3PL billing: the accessorials that never make it onto the invoice

The gap between the work a warehouse did and the invoice it sent is a capture problem, not a pricing one. The seven charges most often missed, and a fix that starts from records the floor already keeps.

EDI & Trading-Partner Onboarding

RosettaNet PIPs vs X12: which one your partner will demand

The standard is chosen by the customer, not the supplier. How a 3A4 lines up with an 850, what the RNIF envelope changes, and how to run both without building two order flows.

From the case files

How this runs in production

Reconciliation · B2B trading partners

Inventory variances that only close when they're actually gone

Two systems held different quantities for the same parts, and the disagreement arrived as a spreadsheet attached to a recurring email. We turned it into a register that remembers — and that nobody is allowed to close by hand.
Integration · Inbound logistics

Knowing where inbound freight actually is

Inbound shipments were tracked by opening carrier websites one tab at a time. We replaced the tabs with live carrier integrations and a workflow that routes exceptions to the person who can fix them.
Planning · Outbound fulfilment

Turning a flat order backlog into a plan the floor can pick

A daily backlog feed said what had been ordered — not what could be built, released or picked. We built the pipeline that turns it into a wave plan, a queued pick order, and a screen that says where each one got to.
