Founder · posbull.com
G Paul runs a 6-site research portfolio covering SaaS niches that small businesses actually buy: POS systems, loyalty programs, QR code tools, review management software, WordPress hosting for agencies, and email marketing platforms. The portfolio publishes original-research datasets and quarterly pricing audits that SMBs and agencies use for buying decisions.
On POSBull specifically

Coverage includes a vendor processor-fee transparency dataset, head-to-head comparisons (Square vs Clover, Toast vs Lightspeed), feature-filter guides for free POS, omnichannel POS, and restaurant-only stacks, plus a quarterly pricing report tracking real fee changes (Square's recent 3.3% online hike was caught here first).
