The verdict in three sentences
For an office supplies distributor serving 900 companies in Miami, a B2B store with an order approval workflow costs roughly 14,500 to 35,500 USD in 2026 (45,000 to 110,000 TND in our Tunis projects). The real commercial lever is not the online catalogue, it is letting each of the buyer's departments order on its own, within a capped budget, with manager approval and net-30 payment. That convenience lifts the average order from about 122 to 167 USD and locks in accounts against competitors still selling by phone and paper purchase orders.
Why hierarchical approval changes the customer relationship
In a 200-employee client company, supplies are ordered by an assistant who gathers requests by email, copies them into a purchase order, gets it signed by the office manager and then sends it to the distributor. The cycle takes 3 to 5 days and produces grouped orders that are late and often incomplete.
With a built-in approval workflow, each requester (front desk, accounting, workshop) fills a cart from their company's negotiated catalogue. The order is routed automatically to the right approver based on simple rules: under 100 USD, auto-approved within the department budget; between 100 and 480 USD, approved by the department head; above that, dual approval by administration. The buyer keeps control, departments gain autonomy and the distributor receives more frequent orders.
| B2B feature | Essential tier | Advanced tier | Complete tier |

Metrics to track after launch
The project is steered with a few simple figures, compared with the phone and purchase order baseline. The ballparks below come from B2B distributors we have worked with; they remain 2026 estimates.
| Indicator | Before (phone, email) | After 6 months online |
|---|---|---|
| Average order value | 122 USD | 167 USD |
| Order frequency per active client | 1.1 per month | 1.6 per month |
| Time from need to order | 3 to 5 days | Under 24 h |
| Order entry errors | 4% of lines | Under 0.5% |
| Sales admin entry time per order | 12 min | 2 min |
| Share of clients ordering online | 0% | 35 to 45% |
| Payments later than 30 days | 18% of invoices | 11% with automatic reminders |
The higher order value comes from three effects: departments add forgotten consumables themselves, the catalogue suggests related items (toner with printer, binders with dividers) and orders are no longer held back by paperwork.
Net-30 payment: framing the credit exposure
Deferred payment is expected by business buyers, but it exposes the distributor. The platform must show each client's outstanding balance, automatically block a new order above the agreed limit and trigger reminders at day 25, 35 and 45. For new clients, card payment or ACH at order can be required for the first three months. Invoices must meet local tax rules, including sales tax handling and exemption certificates where they apply.

Sam, sales director of an office supplies distributor in Miami, launched the Advanced tier for about 25,000 USD. After six months, 360 of his 900 clients order online, on average 1.5 times a month, so 540 orders a month. With the average order up from 122 to 167 USD, the gain is 45 USD per order, or 24,300 USD of extra revenue a month. At a 22% gross margin, that is 5,346 USD of additional monthly margin: the project pays back in under 5 months, before counting the 10 minutes of entry time saved on every order by sales admin.
FAQ
Must all clients move online at launch?
No, expect 35 to 45% of active clients online after six months. Start with the 100 most regular accounts, supported by sales reps, before opening to everyone.
Can we load each client's negotiated prices?
Yes, price lists are imported from the ERP or a spreadsheet. For 900 clients with 3,000 SKUs, the initial import usually takes 1 to 2 weeks.
What happens when an approver is away?
The Complete tier handles out-of-office delegation. On other tiers, a reminder is sent after 24 h and the order escalates to the next approver after 48 h.
Will the platform work with our current ERP?
In most cases, yes, via API or scheduled file exchanges. The connector costs about 3,200 to 8,000 USD depending on the ERP and sync frequency.
How do we stop a department overspending its budget?
Each department gets a monthly or annual budget. Above 90% consumed, the requester is warned, and any out-of-budget order automatically switches to dual approval.
