price_check

Frequently asked questions
What is Resale Intelligence?
expand_more
Resale Intelligence is software for shops that buy and sell used phones, tablets and computers. It shows the most you should pay, based on what your shop has actually sold, works out the true profit on every unit after repairs and fees, and warns you about slow stock before your cash gets stuck.
Read more: Features
Which shops is it for, and which products does it support?
expand_more
It suits used phone and tablet shops, computer and laptop shops, dealers and multi-branch stores, and pawn shops that buy and sell goods. The catalog covers phones, tablets, laptops/MacBooks and desktop computers. The pawn module and gold shops are not available yet. The shared catalog currently lists 119 models and 421 specs from 11 brands.
Read more: Phone shop
How does it help me set a buy price?
expand_more
It takes the median price your shop actually sold the same model and spec for, adjusts it for grade, battery, official or grey import and data age, then deducts repairs, fees, holding cost, a risk reserve and your minimum profit. The result is Safe Buy, shown with a confidence score and sample size. If data is thin, it says so. It supports your decision; it is not a price guarantee.
Read more: Methodology
Can a new shop with no sales history use the valuation?
expand_more
Yes, but confidence starts low. The system only uses your own shop's data, so import past sales from Excel or record the listed prices you see. If there is still too little data, it shows no price and tells you the data is not enough yet.
Read more: Valuation
How does it stop me buying a duplicate or problem device?
expand_more
Scan the IMEI with your phone camera: the system checks the number is valid and blocks a second intake of a device still in stock. The inspection checklist warns about an IMEI mismatch or an iCloud/Google account lock, and seller details are stored encrypted.
Read more: How to check a phone's IMEI before buying (checklist)
How is true profit different from sale price minus purchase price?
expand_more
True profit deducts every cost of that device, including repairs, batteries, parts, shipping and card or platform fees. Each cost sits in a ledger that cannot be edited after the fact, and the system shows margin, ROI and profit per day for every device.
Read more: How to calculate true profit on used phones
Can we move our data over from Excel?
expand_more
Yes. Import your existing stock, customer list and past sales from an Excel or CSV file yourself. The system matches the columns, checks for duplicates, shows a preview before you confirm, and lets you roll back the whole batch within 30 days.
Does it work on a phone? Do I need to install anything?
expand_more
Nothing to install: it runs in the web browser on a phone, tablet or computer. Screens are designed for phones first, you can scan IMEIs with the camera, add it to your home screen as an app (PWA), and use it in Thai or English.
Is my shop's data safe? Can other shops see it?
expand_more
No other shop can see your data. Each shop's data is separated at the database level, customers' personal data is encrypted, owners and admins must use two-factor authentication (2FA), and every important action is recorded in an audit log.
Read more: Security
How much does it cost? Is there a free plan?
expand_more
Yes, there is a free plan you can keep using (users: 2, branches: 1, purchases or sales: 60 a month). Paid plans start at ฿590 a month excluding VAT, Safe Buy valuation starts on Starter, and new shops get every feature free for 14 days.
Read more: Pricing
Does the system guarantee we will not make a loss?
expand_more
No system can guarantee that. The system helps estimate from real data and shows a price range, confidence and risk reasons, so your store can make better decisions.
Can I use the pawn module yet?
expand_more
Not yet. The pawn module opens only after it passes legal review. Pawn shops can already use buying, selling, stock and true profit, and in the system a pawn is always a separate transaction type from a purchase.
Read more: Pawn shop
If we stop using it, can we take our data with us?
expand_more
Yes. The store owner can export all store data as CSV files on every plan, even after the plan has expired.
