Moving a 10-to-60 person distribution, manufacturing, or e-commerce company from disconnected SaaS tools onto Odoo 19 takes 6 weeks when you migrate master SKUs, chart of accounts, CRM pipelines, and warehouse stock in a strict 5-phase sequence. At Qann, we execute full Odoo ERP setups from EUR 1,599 fixed fee without writing fragile custom modules that break on upgrades.
Look at how a typical 25-person product company runs before an ERP cutover. Sales reps track wholesale leads in HubSpot or Pipedrive. Retail orders come through Shopify or WooCommerce. Purchase orders live in Google Sheets. Warehouse staff print shipping labels in Sendcloud, and every Friday afternoon the operations manager spends four hours reconciling CSV exports for the bookkeeper.
You do not have twelve software tools. You have twelve databases that disagree with each other every Friday at 4 PM.
01Why traditional ERP implementations take 9 months and fail
When founders hire a traditional ERP agency, the agency bills by the hour. That creates a perverse incentive: the more custom fields, custom workflows, and custom Python modules they write, the more they bill you. Six months later, you are EUR 40,000 poorer, your team hates the interface, and you are trapped on an old version of Odoo because upgrading would break 40 custom plugins.
We work as operators first (Empty Vapes, NOIDS, Martian Grow). Our rule is simple: configure standard Odoo 19 for 95% of the workflow, clean the data ruthlessly before import, and never customize a screen until the team has used standard Odoo in production for 30 days.
| Migration Dimension | Traditional Hourly ERP Reseller | DIY Founder Weekend Attempt | Qann 6-Week Operator Cutover (/services/systems) |
|---|---|---|---|
| Timeline to live operations | 6 to 12 months | Stalls halfway through SKU import | 6 weeks in 5 fixed milestones |
| Pricing model | EUR 15,000 to EUR 60,000 open-ended hourly | "Free" until accounting breaks | From EUR 1,599 fixed fee (scoped upfront) |
| Data hygiene before import | Dumps legacy duplicates straight in | Imports messy Excel sheets with typos | Deterministic deduplication of contacts, tags, and SKUs |
| Custom code debt | Heavy custom modules that block upgrades | Random third-party app store plugins | Standard Odoo 19 core + clean API webhooks |
| Post-launch handover | Locks you into a costly annual retainer | Nobody knows how to close the month | Full admin keys, SOP runbooks, or optional EUR 449/mo ops |
02The 6-week Odoo 19 migration checklist
Whether we are consolidating B2B wholesale hardware (Empty Vapes) or connecting multi-region DTC fulfillment (NOIDS), every migration follows the exact same six-week calendar:
Week 1: Process Audit & Subscription Kill-List
We list every software subscription on your bank statement and map every spreadsheet your team touches. Each tool gets classified into one of three buckets: Retire into Odoo 19 (CRM, Inventory, Purchase, Invoicing, Project), Connect via Webhook (Shopify, Stripe, 3PL warehouse), or Keep Standalone (Google Workspace). We lock the chart of accounts with your accountant before touching a product row.
Week 2: Master SKU, BOM, and Contact Deduplication
An ERP is only as trustworthy as its master records. Before importing a single row into Odoo 19, we run your legacy customer lists, supplier catalogues, and product tables through an offline deduplication harness:
- Contacts (
res.partner): Merge duplicate company records by VAT number, normalized domain, and email so sales history lands on one clean account card. - Products & Bills of Materials (
product.template): Standardize SKU codes, barcodes, HS customs codes, units of measure, and multi-currency price lists (EUR,USD,GBP). - Tag Taxonomy: Replace 200 chaotic ad-hoc CRM tags with a clean 3-facet taxonomy (
Channel,Product Line,Region).
Week 3: Core Configuration & Staging Cutover
We configure Odoo 19 in a staging environment mirroring your live legal entities: multi-warehouse locations, automated reorder rules, EU OSS/reverse-charge tax mapping, and B2B quotation templates. No dummy data is used; we load your cleaned master records and run real test orders from quote to bank reconciliation.
Week 4: Storefront, 3PL, and Payment Connections
Next, we wire the outside world into Odoo 19 (/services/automation). Shopify or WooCommerce orders flow into Odoo Sales automatically; inventory levels sync back within seconds; Stripe and bank feeds auto-match against open invoices with heartbeats that alert on Slack if a webhook ever stalls.
Week 5: Role-Based Team Training & Parallel Run
Warehouse staff do not need to see accounting menus, and sales reps do not need warehouse configuration screens. We strip user permissions down to the exact buttons each role needs, write plain-English SOP checklists inside Odoo Knowledge, and run five days of parallel operations alongside your legacy stack.
Week 6: Hard Cutover, Opening Balances & SaaS Cancellation
On cutover weekend, we run a final physical stock count, post opening inventory and ledger balances, switch live webhooks to production, and help you cancel the 8 to 12 SaaS tools you no longer need.
03See what a clean Odoo 19 backbone costs
We publish our exact rates on /services/systems: ERP & CRM Setup starts from EUR 1,599 fixed fee, System Connections run at EUR 75/hr, and Managed Operations start from EUR 449/mo. If your team is still reconciling spreadsheets every Friday, send us your current tool stack and we will map your 6-week migration plan.
