The best tool depends on your volume. For a handful of booths, a pen and your phone camera are enough. Once you rack up dozens of suppliers over several days, you need a tool that links photo + quoted price + MOQ + supplier on the spot, works offline, and then lets you compare the same product from one booth to the next. This comparison walks through the five families of tools buyers actually use on the floor, with their real strengths and weaknesses — none of them dressed up.
At a show like the Canton Fair, which gathers over 25,000 exhibitors across 1.55 million m² in three phases, finding products is not the hard part. Organizing what you see fast enough to decide once you're home is. That is what a tool is for.
What a field-sourcing tool has to do
Before comparing, let's set the criteria that actually matter when you're walking the aisles, badge around your neck, pockets full of business cards.
- Capture speed: how many seconds to log one product? At a booth you rarely have more than 15–20 seconds before the sales rep takes over.
- Offline: exhibition-hall Wi-Fi is saturated and foreign mobile data is expensive and flaky. The tool must work with no signal.
- Links photo + price + supplier: a photo with no quoted price (FOB, the ex-factory price before shipping), no MOQ (minimum order quantity) and no booth name is worthless three days later.
- Cross-supplier comparison: line up the same item seen at three exhibitors, in the same currency, to decide.
- Landed cost / CBM: estimate the delivered price (landed cost) and the volume in cubic meters (CBM) to know whether it fills a container.
- Purchase-order (PO) export: turn a shortlist into an order you can send to the supplier.
Option 1 — Pen + business cards + phone camera
The default method, and let's be honest: it works for small volumes.
Pros. Zero cost, zero learning curve, no software battery to manage, obviously works offline. Nothing beats jotting a price in a notebook when you only visit five booths.
Cons. The link breaks on the way home. You come back with 200 photos in your camera roll, a stack of cards stapled to scraps of paper, and no reliable way to say which photo goes with which price and which MOQ. Cross-supplier comparison is impossible without re-entering everything. This is where most buyers lose their best leads — not at the show, but in the 72 hours that follow.
Option 2 — Spreadsheet (Excel / Google Sheets)
The natural "pro" step after the notebook.
Pros. Structured, familiar, free or nearly, calculated columns to total price × quantity. Excellent after the show, sitting down calmly.
Cons. Typing into a grid on a phone, standing up between two booths, is slow and error-prone. Google Sheets needs a connection to sync (offline mode exists but stays fragile on a show floor). Above all, a spreadsheet doesn't natively handle photos: you end up juggling the camera roll and a spreadsheet, and the photo↔row link gets lost. For comparison and landed-cost math, though, the spreadsheet remains a solid desk tool.
Option 3 — Generic note / scan apps (Notion, CamScanner, card scanners)
Plenty of buyers cobble something together with consumer apps.
Pros. Business-card scanners (CamCard, Business Card Reader…) do one precise job well: read a card and extract name, phone and company by OCR. CamScanner cleanly digitizes a paper catalog.
Cons. These tools aren't built for sourcing. CamScanner is still free but stamps exports with a watermark, and locks OCR, cloud and batch behind Premium (~$49.99/yr). A card scanner files your contacts but doesn't tie a contact to a product, a price and a photo. Notion is flexible but slow to fill by thumb on mobile and poor offline. You get clean fragments — contacts here, scans there — but never the unified product record you need to decide.
Option 4 — B2B marketplaces (Alibaba, Made-in-China, Global Sources)
Many buyers reach for "there must be an app for that." There is — just not for this.
Pros. These are giant catalogs. The Global Sources app, for instance, helps plan your visit, search an exhibitor by booth number, and scan a card to pre-fill registration. Useful upstream to spot suppliers and frame a price range.
Cons. They are catalogs, not capture tools. They list the supplier's online offer — not the price quoted verbally at their booth, which often differs, nor the exact sample sitting on the table in front of you. You can't create your own record for "this model, at this price, from this exhibitor." And many of the best factories at a show have only a minimal online presence. The marketplace complements your prep; it doesn't replace field note-taking.
Option 5 — Purpose-built field-sourcing app (like Fairloop)
A recent category: apps built for the single act of "capturing a product at a booth."
Pros. Unified, fast capture: one photo, the quoted price, the MOQ, the supplier, in a single record, in under 15 seconds, offline, syncing when you reconnect. Then comparison of the same product across booths in a reference currency, landed-cost and container-fill (CBM) math, and PO generation. This is exactly the gap the four options above leave open: the link that holds from the aisle all the way to the order.
Cons. You have to install the app and adopt a habit. It's a niche tool — pointless if you only visit two or three booths a year. And it replaces neither the marketplace for discovery nor the spreadsheet for fine accounting. To be clear: for very small volumes, the notebook stays unbeatable in simplicity.

|---|---|---|---|---|---|---|
| Pen + cards + photo | High (small volume) | Yes | No (link lost on return) | No | No | No |
| Spreadsheet (Excel/Sheets) | Low on mobile | Partial/fragile | Manual, no photo | Yes (at desk) | Yes (formulas) | Manual |
| Note/scan apps (CamScanner, Notion) | Medium | Variable | No (separate fragments) | No | No | No |
| B2B marketplace (Alibaba, Global Sources) | N/A (catalog) | No | No (online offer, not field) | Partial (online prices) | No | No |
| Purpose-built app (Fairloop) | High (<15 s) | Yes | Yes | Yes (ref. currency) | Yes | Yes |
How to choose by profile
You visit a few booths, once a year
Stick to pen + photo, maybe copied into a spreadsheet in the evening. No need for a dedicated tool.
You run a real sourcing trip (dozens of suppliers, several days)
This is where the link breaks. A tool that captures fast, offline, and unifies photo/price/supplier saves you the hours of re-entry on your return — and, more importantly, stops you from losing leads. Prep discovery on a marketplace, capture on the floor with a purpose-built app, and keep the spreadsheet for fine analysis.
You're a team
The question becomes: how do you merge what three people captured at three booths? Here, a shared tool (synced records) beats any pile of notebooks and camera rolls.
FAQ
What is the best tool for sourcing at trade shows?
There isn't a single one — it depends on volume. For a few booths, pen and photo are enough. For a trip with dozens of suppliers, a tool that captures photo + price + MOQ + supplier on the spot, offline, then compares and computes landed cost, prevents lost leads on your return. The marketplace is for prep, not capture.
Is Excel enough to organize trade-show suppliers?
Excel is excellent at a desk for comparison and math, but poor for standing data entry between booths: slow by thumb, fragile offline, and it doesn't link photos. Many buyers capture on the floor with a fast tool, then export to a spreadsheet for analysis. The two are complementary, not competitors.
Can the Alibaba or Global Sources apps capture products?
No: they are catalogs, not capture tools. They help you spot exhibitors and plan the visit, but they list the supplier's online offer — not the price quoted verbally at their booth nor the sample in front of you. You can't create your own record for "this model, this price, this exhibitor."
How do I organize what I bring back from the Canton Fair?
The critical point is linking each photo to its price, MOQ and supplier during the show, not after. Then bring everything into the same currency to compare the same item across booths, estimate landed cost and CBM volume for the container, and turn your shortlist into a purchase order. See also our Canton Fair 2026 guide.
Is a business-card scanner enough?
It does one thing well — pull the contact details off a card — but doesn't tie that contact to a product, a price and a photo. You get a clean address book, not a usable product record to decide with. It's a useful complement, not a complete sourcing tool.
Fairloop is the "purpose-built app" option in this comparison: offline capture in under 15 seconds, same-product comparison across suppliers, landed cost, CBM and purchase order — $99/year, 24h free trial. If your problem is losing your best leads between the booth and home, that's exactly the gap it fills; for two booths a year, keep your notebook.
