The Setup
A single-location dispensary didn't have an AP department. They had a store manager who did AP on the side. Every week looked the same: download invoices from email, enter line items into a spreadsheet, compare amounts against what he remembered receiving (no formal reconciliation), write checks by hand, drive to the post office, then enter everything into QuickBooks. Vendor has a question? He'd take the call between customers on the floor.
15 hours per week. Almost two full workdays. Not because he was slow — because the process was slow. Manual data entry, manual verification, manual payment, manual recording. Every step done by hand, every week, for 35+ vendors.
The store suffered. He was the best person on the floor — the one customers asked for, the one new staff looked to for training. Instead, he was in the back office matching invoices to memory.
What Changed
During the 60-day pilot, we rebuilt this store's entire AP workflow from the ground up. Here's how the transition played out:
- Week 1: We onboarded all 35+ vendors. Each vendor was given a ShelfSpace email address for invoices. Metrc was connected. QuickBooks was linked.
- Weeks 2-3: Invoices started flowing through ShelfSpace. We parsed every line item, matched against Metrc deliveries, checked for duplicates, and cross-referenced credits. The manager received a clean weekly summary: "Here are your invoices, verified and ready. Credits applied. Amounts adjusted. Approve to send payments."
- Week 4+: The manager's entire AP workflow became: open ShelfSpace, review the payment summary, tap approve. Checks go out. QuickBooks syncs. Done. 15 minutes.
No spreadsheets. No hand-written checks. No post office runs. No vendor calls. We handle all of it through managed accounts payable.
What the 15 Hours Were Actually Costing
Beyond the raw time, the manual process was bleeding money and creating risk the manager couldn't see:
- Invoice entry errors — typos, wrong amounts, transposed digits. The manager caught some, missed others. When you're entering 35+ invoices by hand every week, mistakes aren't a matter of if. They're a matter of how many.
- No Metrc verification — deliveries were checked against memory, not manifest data. In the first month, we caught $3,200 in discrepancies he'd been missing. Invoices that didn't match what was actually received. Quantities off. Prices different from what was agreed.
- No credit tracking — vendor credits were "I'll remember to deduct that next time." They didn't. Credits for returns, damaged goods, pricing adjustments — all falling through the cracks. Credit recovery alone justified the switch.
- Vendor calls during business hours — interrupting floor operations, frustrating customers. Every call pulled the manager away from the register, away from training, away from the work that actually grows the business.
- QuickBooks lag — entries happened 2-3 days after payments. The books were always behind. Month-end close was a scramble of backfilling and reconciliation.
The 15 hours weren't just time. They were errors, missed credits, and a store manager pulled away from what he's actually good at.
The Result
15 hours to 15 minutes. A 98% reduction in AP time.
The manager is back on the floor full-time. He trains new staff. He works with customers. He manages inventory. The back office runs itself — because it's not the back office anymore. It's ShelfSpace.
In the first month alone, we caught $3,200 in invoice discrepancies the manual process had been missing. Over a year, that's $38,000+ in vendor overpayments avoided — on top of the time savings.
He was the best person in the store. We put him back on the floor.
