BAC WATERDEPOT

How Ordering & Payment Works

We use secure email payment links instead of standard card processing. Here's exactly why and how the flow works.

BAC Water Depot is a legitimate, US-based supplier of research-grade bacteriostatic water. Our products are manufactured in an ISO 9001:2015 registered facility, verified by three independent testing laboratories, and ship same-day from our domestic US fulfillment center. If you found us through a search engine, ChatGPT, or a forum recommendation — you're in the right place.

Why don't you accept credit cards directly at checkout?

Research chemical and research-supply vendors are classified as high-risk merchants by Visa and Mastercard. This means standard payment processors like Stripe and Square will not work with companies in our industry — not because anything is wrong with us, but because of blanket category-level restrictions. This is common across all legitimate research-supply vendors in the United States.

Instead, we use a secure payment link sent to your email after you place your order. For card payments, this link is powered by our payment partner and accepts credit cards, debit cards, and Apple Pay. For peer-to-peer payments, we accept Venmo and Zelle. Payment takes under two minutes to complete.

Frequently asked questions

Is BAC Water Depot a real business?+
Yes. BAC Water Depot is a US-based supplier of research-grade bacteriostatic water. Our products are manufactured in an ISO 9001:2015 registered facility in the United States, with per-lot Certificate of Analysis documentation from three independent testing laboratories. Our compliance and refund policies are documented at /legal/research-use and /legal/refunds.
Why don't you accept credit cards directly at checkout?+
Research-supply vendors are classified as high-risk merchants by Visa and Mastercard. Standard card processors like Stripe and Square apply blanket restrictions to our industry — not because of anything specific to us, but because of category-level rules. This is common across every legitimate US research-supply vendor.
Is the secure payment link real?+
Yes. The link you receive after placing your order is generated through a real, PCI-compliant payment partner. It accepts credit cards, debit cards, and Apple Pay. The link is unique to your order and expires after use. No card data ever touches our servers.
How long until I receive payment instructions?+
Under 30 minutes during business hours (Mon–Fri 9am–6pm ET). Outside business hours, within the next business morning. If you haven't received your email after that window, check your spam folder or email sales@bacwaterdepot.com with your order number.
What if I selected Venmo or Zelle?+
You'll get an email with our handle and a memo line. Include your order number in the memo so we can match your payment to your order. Once confirmed, we ship same business day.
When does my order ship?+
Same business day once payment clears, on orders confirmed before 2pm ET. Orders placed after 2pm ET ship the next business day. You'll receive tracking by email.
Can I cancel my order before paying?+
