In short: against Erplain, on November 1, 2026 I recorded Zoho Inventory, free then 29 € per month paid annually, Odoo Inventory, free on its own then 19.90 € per user, and Dolibarr, free or 14 € HT per user at DoliCloud. Erplain suits a business that buys, stores and resells, mostly to professionals. Custom software doesn't beat the 4,140 € HT of Erplain for three people over three years, unless the subscription makes you re-enter everything every day.
Erplain often comes up when a small business finally decides to move its inventory out of the spreadsheet. I know the scene: the shared file that two people edit at the same time, the warehouse that no longer matches the store, the supplier order sent by email and never reconciled with what actually arrived. Before advising anything, I reviewed Erplain’s pricing page on November 1st, 2026, module by module, as well as those of three other software solutions that also display their prices. Here’s what Erplain costs, who it’s right for, what might make you hesitate, three priced alternatives, and when a custom-built tool makes sense.
What Erplain Costs in 2026
Erplain is structured like a menu, according to its pricing page , as of November 1st, 2026. The base plan costs 59 € HT per month with annual billing, requiring a 12-month commitment and including two free months. It includes one user and 1,000 orders per month, plus 0.03 € HT per additional order. Inside, you get quotes, orders, delivery notes, electronic invoices, stock levels, inventory via barcode scanner or phone, restock alerts, stock valuation, and synchronization with Pennylane, QuickBooks, and Stripe.
Monthly billing adds 20% to all costs. The base plan then costs 70.80 € HT, with no commitment and automatic monthly renewal. Each additional user costs 14 € HT per month with annual billing, or 16.80 € HT if billed monthly.
The rest is priced module by module, with annual monthly pricing: multiple storage locations 14 €, supplier orders and receipts 14 €, kits and packaging 9 €, batches, serial numbers, and expiration dates 29 €, user permissions 24 €, activity log 24 €, Shopify integration 9 €, API 39 €. The publisher highlights two typical setups: 138 € HT per month for 3 users with multiple locations, kits, purchases, and advanced pricing, and 257 € HT for 5 users with nearly all modules. The trial lasts 14 days without a credit card; one hour of onboarding is included, with additional hours at 80 € each.
Who Should Choose Erplain
A business that buys, stores, and resells products—especially to other professionals: a wholesaler, a distributor, a manufacturer supplying stores, or a Shopify e-commerce seller also operating in B2B. On its website, the publisher highlights food, automotive, materials, medical equipment, and fashion.
If you’re one or two people, with a single storage location, and your day revolves around ‘quote, order, delivery, invoice,’ the 59 € HT base plan covers most needs, including electronic invoicing and integration with Pennylane or QuickBooks.
What Might Make You Hesitate
The price rises with team size and added modules. Add three people, a warehouse and a store, and supplier orders to process in the tool: 59 €, plus two users at 14 € each, plus multi-location and purchases at 14 € each, totaling 115 € HT per month, or 1,380 € HT per year. Paid monthly, the same setup costs 138 € HT. For products with expiration dates, add 29 € for batch tracking and expiration dates.
Purchases aren’t included in the base plan. Supplier orders and receipts are a separate 14 € per month module—daily essentials for a distributor.
The commitment depends on how you pay. The page displays « no commitment » in several blocks, but the price of 59 € comes with the note « 12-month commitment ». Without commitment, it’s the monthly rate, 20% more expensive. Read the fine print under the price.
The order limit. 1,000 orders per month are included, purchases included: a full sale counts as one, a full purchase as well. Beyond that, it’s 0.03 € per order. An online store with 1,500 sales in a month pays 15 € extra: little, but variable.
What the site doesn’t mention. Nothing about equipment rental, including its checkout, return, and condition upon return. Among online stores, only Shopify appears in the integrations listed as of November 1, 2026: no WooCommerce, no PrestaShop. If you rent equipment, my test for event equipment rental providers compares software designed for rentals.
Three alternatives to Erplain, with their prices
Prices checked on November 1, 2026, on each vendor’s page. Features vary from one software to another: compare based on your needs, not just the introductory price.
Zoho Inventory charges per company, not per user. Its French page shows a free plan for 1 user, 2 locations, and 50 orders per month. Standard costs 29 € per month paid annually, or 39 € monthly, for 2 users, 2 locations, and 500 orders. Professional, at 79 € or 99 €, allows 3,000 orders and 4 locations, with batches and serial numbers; barcode generation comes with Premium, at 129 €. According to its detailed pricing grid, an extra user costs 7.50 € per month when paid annually. The French page doesn’t specify whether prices are VAT-inclusive or exclusive. 14-day trial without a card.
Odoo Inventory is free as long as it’s used alone. On its pricing page, Odoo guarantees that one app remains free, with no user or time limits, hosting included. As soon as you add Sales or Invoicing, it’s the Standard plan: 19.90 € per user and per month paid annually (12-month discount, original price 24.90 €), or 24.90 € monthly. The page doesn’t specify VAT inclusion, and setup costs are not included. Inventory features: multiple warehouses, barcodes and QR codes, batches, serial numbers, cycle counting.
Dolibarr is open-source software, free if you install it yourself. Hosted by DoliCloud, it costs 14 € VAT-exclusive per user per month in Basic, with all official modules (quotes, orders, invoices, inventory), or 30 € VAT-exclusive per month plus 15 € per user in Premium, with no commitment, and a 30-day trial. The 2016 Finance Law certificate, upon request, adds 5 € VAT-exclusive per user in Basic. The Stock module manages multiple warehouses, batches, serial numbers, and expiry dates.
For three people, paid annually, this comes to 36.50 € per month with Zoho in Standard (but with 2 seats and 500 orders), 59.70 € with Odoo the first year with inventory and sales, 42 € VAT-exclusive with DoliCloud, compared to 115 € VAT-exclusive for the Erplain configuration described above. The Erplain publisher also sells Stockpit, the standalone stock module connected to Pennylane or Sellsy: 19 € VAT-exclusive per user per month, or 39 € with multiple storage locations and purchases.
And if none of these fit: the custom tool
Market software handles the buyer, store, resell journey well. They struggle with what’s unique to you: the truck used as a depot that gets recount upon return, rented equipment that comes back damaged, or the inspection step that no module accounts for. At publisher Kodeva, I developed StockPME, a custom stock management software: QR code labels, multiple warehouses and locations, and a history of every movement. It still runs in SMEs with 20 to 200 employees. I explain elsewhere how inventory via QR codes and multiple depotsworks, phone in hand.
On pricing, an add-on connected alongside your subscription costs between 2,500 € and 7,000 € once: for example, a scanning screen for the truck that sends each exit back to Erplain via its API. A full management software ranges from 5,000 € to 15,000 € upfront, then 100 € to 300 € per month for maintenance, hosting, and backups included, and you own the code. Over three years, the Erplain setup at 115 € VAT-exclusive per month totals 4,140 € VAT-exclusive. Custom solutions don’t win on this figure: they justify themselves when the subscription forces you to re-enter daily what it can’t handle. My custom software pricing benchmark helps verify a quote.
How to choose in one day
If your industry is listed, start with my free tests by profession: in six questions, they reveal whether off-the-shelf software suffices. Then simulate a real day with the software during its trial: a customer order received by email, the delivery note, an incomplete supplier delivery to process, a transfer from the reserve to the truck, the invoice, and finally, counting ten references over the phone. Note everything you re-enter elsewhere. Recalculate with the actual number of users and the modules truly needed—that’s the price to compare.
