Who can integrate our WMS, TMS and ERP into one reporting layer?

• 01Extraction is the easy half. A WMS order id, a TMS load or BOL number and an ERP sales-order number are three different keys at three different grains: one sales order can ship as several deliveries, and one truck can carry lines from several orders. Until a crosswalk resolves that many-to-many relationship, three connected systems produce three contradictory OTIF numbers instead of one.
• 02The extraction surface differs by system and is what actually sets the timeline. An on-premises WMS is normally read from a SQL replica or a vendor interface/staging table via an on-premises data gateway. A cloud TMS or visibility platform is usually a paginated REST API, and some publish only scheduled CSV or EDI 214/990 files to SFTP or blob storage. ERP depends on the product: SAP ECC is usually read through its extractors or a replica rather than production, Oracle EBS through a read replica, Dynamics 365 Business Central through its OData/API surface or Dataverse. Which surface your instance actually exposes is established in discovery, not assumed from a connector list.
• 03Four disagreements show up on nearly every one of these projects: unit of measure (ERP in cases or pallets, WMS in eaches, TMS in weight and pallet positions), timestamps (warehouse local time against carrier-reported UTC against an ERP posting date on a fiscal calendar), freight cost (a TMS accrual against the carrier invoice posted in ERP), and records restated after returns or cancellations. Each needs a written rule before a tile can be built on it.
• 04Connect ERP first, then WMS, then TMS. ERP owns the conformed dimensions — customer, item, site, company code — and WMS and TMS rows have nothing to join to until those exist. TMS goes last because it is the most fragmented: several carriers, often a 3PL in between, and the weakest access guarantees. A multi-entity ERP estate needs a conformed chart of accounts before the financial side reconciles at all.
• 05Two suppliers bill you. Microsoft charges Fabric capacity (F2 is the smallest SKU) plus a per-consumer Power BI licence below F64; Folio3 charges implementation and ongoing operation, quoted across Starter, Growth and Enterprise. The gateway itself is a free download, but it needs a host someone patches and sizes. What moves the quote is the number of source systems, how many legal entities consolidate, and whether the WMS schema is documented.
• 06Honest limit: if your WMS or TMS data sits with a 3PL who will only give you portal exports, there is no reporting layer to build — a spreadsheet a person downloads is not a source. The same applies to a heavily customised on-premises WMS with no documented schema and no vendor support, where discovery takes longer than the build and the engagement runs six to eight weeks or more.
